Question

In a purse, there are equal number of Rs.5, Rs.2 and Re.1 notes and the total value is Rs.9,600, find the total number of notes

Answer 1

Answer:

We have a total of 3200 no. of notes in the purse

Step-by-step explanation:

Let x be the total number of notes.

According to the question there are equal number of notes of all domination rs5, rs2 and rs1,

so, we have x/3 numbers of each notes. (we have three types of notes).

Now, using the condition that we have total value of all notes rs9600

5(x/3) + 2(x/3) + 1(x/3) = 9600

Solving for x in the a above equation.

5x/3 + 2x/3 + x/3 = 96000

=> 9x/3 = 96000

=> 3x = 9600

=> x = 3200

This gives us the answer to the question,

We have a total of 3200 no. of notes in the purse

Answer 2

ANS

There are a total of 3600 notes in the purse.

EXPLANATION

All the units are in Rs ,So we don't need to change any unit.

It is given in the question that there are equal number of notes of all values ie Rs 5, Rs 2 and Rs 1

Let x be the number of notes.

So

• Amount in Rs 5 is equal to $5x$
• Amount in Rs 2 is equal to $2x$
• Amount in Rs 1 is equal to $1x$

Total amount=

$5x+2x+1x$

It is given in the question that Total amount is 9600Rs

So

$5x+2x+1x=9600$

$8x=9600$

$x=1200$

So each amount has 1200 notes . As there are three denominations (Rs5 Rs2 Rs1) the total number of notes become -

$1200×3=3600$

So the total number of notes are 3600.

Generally these questions involve different ratios.ie we are given the ratio of the number of coins .And the total amount is given.

Also the units are different so we have to change into units that are easy to calculate according to the question. You can check out below in the given links.
